*^* The illustrations are all drawn to scale with the aid of the camera Incida, and the magnifying power 

 used is attached to each figure. 



The diameter of the object in any of the figures may readily be obtained by comparing them with the one- 

 thousandth of an inch scale placed at the foot of each plate. 



These plates have been engraved in the Office of the Surveyor-General of India. They are very faithful 

 copies of the original drawings, and will bear favourable comparison with the work of engravers in Europe, who 

 are habitually engaged in this kind of employment. I am under great obligation to the Surveyor-Genei-al and 

 also to the Assistant Surveyor-General, Captain W. G. Murray, under whose immediate superintendence the work 

 has been done.
